The pci bar assignment has radically changed, from a linear scan and
assigning addresses to bars in scan order (and just skipping the the
ones it can't assign) to a two-pass algorithm which sorts the bars by
size.  Result is (a) better packing and (b) seabios figures it can't fit
bars before it starts assigning.  It also has full bridge support now.

Look at /proc/iomem with old and new bios to see the difference.

/me wonders that the guest boots at all.

Yes.  Set vram to 32mb for both cards should do the trick.

Don't know.

cheers,
